New in Internet Services Performance improvements Reporting of configuration failures has been improved on the Internet Services console, and you can get more detail for troubleshooting purposes by setting DBG_InetCfg in the inetsvcs.cf configuration file. Also, after a failure, FirstClass attempts to reconfigure after one minute. There are also some new menu commands that let you dump the current configuration. Messaging • SMTP message attachments Internet Services supports a message attached to another message, making an incoming attached message look like an attached FirstClass message. • IMAP IDLE support This command lets users (mostly mobile users) stay connected to the IMAP server indefinitely. This way they will see new messages as they arrive, rather than waiting for a polling cycle. HeaderMatch Added the following HeaderMatch switches: •       "usecomplianterrorcodes" controls whether Internet Services always sends error pages with their actual protocol compliant error codes. More •  "commontemplates" used to set a common fallback template set for a given template alias. More Inetsvcs.cf OS X and Linux versions of Internet Services support a set of signals that can be sent to the Internet Services process, which triggers certain commands. The actions can be specified with entries in the inetsvcs.cf file, in the Config section, using the following keywords: • SET_SIGUSR1 • SET_SIGUSR2 • SET_SIGINFO • SET_SIGVTALRM More New variable Added a #BYTESXFERED builtin variable for rules.mailrules use, updated with the raw bytes presented after the start of the SMTP DATA command. More New in forms •       Basic Internet Setup, Service tab         - Configuration refresh interval field •       Internet Monitor         - Control tab has been broken down into four subtabs
